1 Cor 14:2 For one who speaks in a tongue does not speak to men but to God; for no one understands, but in his spirit he speaks mysteries.
1 Cor 14:3 But one who prophesies speaks to men for edification and exhortation and consolation.
1 Cor 14:4 One who speaks in a tongue edifies himself; but one who prophesies edifies the church.
1 Cor 14:5 Now I wish that you all spoke in tongues, but even more that you would prophesy; and greater is one who prophesies than one who speaks in tongues, unless he interprets, so that the church may receive edifying.
1 Cor 14:6 ¶ But now, brethren, if I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?
1 Cor 14:7 Yet even lifeless things, either flute or harp, in producing a sound, if they do not produce a distinction in the tones, how will it be known what is played on the flute or on the harp?
1 Cor 14:8 For if the bugle produces an indistinct sound, who will prepare himself for battle?
1 Cor 14:9 So also you, unless you utter by the tongue speech that is clear, how will it be known what is spoken? For you will be speaking into the air.
1 Cor 14:10 There are, perhaps, a great many kinds of languages in the world, and no kind is without meaning.
1 Cor 14:11 If then I do not know the meaning of the language, I will be to the one who speaks a barbarian, and the one who speaks will be a barbarian to me.
1 Cor 14:12 So also you, since you are zealous of spiritual gifts, seek to abound for the edification of the church.
1 Cor 14:13 ¶ Therefore let one who speaks in a tongue pray that he may interpret.
1 Cor 14:14 For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
1 Cor 14:15 What is the outcome then? I will pray with the spirit and I will pray with the mind also; I will sing with the spirit and I will sing with the mind also.
1 Cor 14:16 Otherwise if you bless in the spirit only, how will the one who fills the place of the ungifted say the "Amen" at your giving of thanks, since he does not know what you are saying?
1 Cor 14:17 For you are giving thanks well enough, but the other person is not edified.
1 Cor 14:18 I thank God, I speak in tongues more than you all;
1 Cor 14:19 however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.
1 Cor 14:20 ¶ Brethren, do not be children in your thinking; yet in evil be infants, but in your thinking be mature.
1 Cor 14:21 In the Law it is written, "BY MEN OF STRANGE TONGUES AND BY THE LIPS OF STRANGERS I WILL SPEAK TO THIS PEOPLE, AND EVEN SO THEY WILL NOT LISTEN TO ME," says the Lord.
